correct information about how string comparison works
Your instructional text says string comparison is according to ASCII collation order. The Python 3 documentation says, "Strings (instances of str) compare lexicographically using the numerical Unicode code points (the result of the built-in function ord()) of their characters." So your statement is only true for ASCII characters. Why not tell the whole truth?

correct example for if statement with compound condition
The question asks to print the year the album came out. The sample code prints 'This album came out already'. You should make them consistent.

correct the description of the range() function and type
The instruction refers to the "range object." Why not just say (more precisely) that the range type amounts to an (ordered) sequence of integers, and the range() function generates such sequences? This is computer programming. We can be fully exact from the git go. We don't have to gloss or approximate these little truths for the sake of simplification or summarization.

Vague question about range function
The question says, 'Write a for loop the prints out all the element between -5 and 5 using the range function.' You should specify whether the between includes or excludes the lower and upper bounds. English does not have separate words for each of the four possible cases, so using one word for all four cases creates ambiguity that leads to four possible correct answers.

inelegant sample code
In box [13] you define a Rating variable that you don't need. A simpler solution is
PlayListRatings = [10, 9.5, 10, 8, 7.5, 5, 10, 10]
i = 0
while PlayListRatings[i] >= 6:
print(PlayListRatings[i])
i = i + 1
if(i > 1000):
breakNote this example includes a safety mechanism that avoids infinite looping. I would never teach the while loop without warning students about the dangers of infinite looping. . . .

Has anybody figured out how to install Arpack for Julia?
So far I could not get past this issue that is described here:
https://github.com/JuliaLinearAlgebra/Arpack.jl/issues/5without Arpack, Julia's computational ability is hugely limited. If there is not a workaround then people should address this.
Thank you.

A temporary fix for those unable to play with or access their notebooks for long:
If you get a chance try and download all of your relevant notebooks and just go to: https://jupyter.org/try and click on the widget for "jupyter labs" and work on your data there.
It seems to be loading a bit with enough time to download them before crashing again..... but I'm pretty turned off to the fact that it's still kicking me off and glitching pretty bad today. A lot of us have things we need to have work on or some of us actually paid money. It's a bit unfortunate that IBM/support isn't giving anyone answers or even bothering to…
